To all whom t mag/concern:

Be it known that I, HERBERT CHAMPION Harrison,- a subject of the King of Great Britain, residing at Lock ort, in the county of Niagara and State o New York, have invented certain new and useful Improvements in Hexagonal Construction of Radiator-Cells; and I do hereby declare' the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it vappertains toi make and use the same. y

This invention relates to radiators having air cells of a hexagonal shape, and has for its purpose to produce aradiatorwhich will be simpleinfconstruction, eiicient in action,

and one which will have longer water pas@ sages, and therefore be more eliicient in cooling the water than those heretofore pro posed.

To these ends the `invention consists in the novel details of construction and combif nationsv of parts more fully hereinafter dis closed and particularly pointed out in the claims.

Referring to the accompanyin 'drawings forming a. part of this speci cation, in which like numerals designate like parts in all the viewsz-Figure 1 is an elevational view partly in section of a radiator built in accordance with my invention; Fig. 2 is a perspective view partly in section of a portion of the air cells showing the water courses' therebetween; and Fig. 3 is an enlarged end elevational View, partly in section, ofa'plurality of air cells, also showing a water course therebetween.

1 indicates the usual-framework of a radiator, 2 the'usual water chamber provided with a bottom plate 3 having the water passages 4 through which the water enters the zig-zag passages 5 between the hexagonal shaped cells 6 of which the main body of the radiator is composed. In some well known forms of construction, however, the-top and bottom1 plates 3 may be dispensedv with.

In producingA my hexagonal cells, I take a thin strip of metal and fold it uponitself a plurality of times to form the plaitsiS and bend the metal at the point 9 outwardly as it leaves.` one end of the plait 8 lat an angle of 120 to said lait, while at a distance equal to the lengt ofthe plait 8 and at the point 10, I bend the metal again inwardly and at an angle of 120 to itself. I next, at-

the jpoint 11, equal to another distance of the length` of the plait 8, preferably indent the metal as shown, and again bend ythe same outwardly at an angle of 120 to itself, and finally, at the point 12, equal to the distance of the length of the plait 8, I further bend vthe metal inwardly at 120o to itself. At the point 13, equal to thel length of the plait 8, I next form a second plait 8 and repeat the foregoing operations until .a strip of sulficientleugth is produced. I next place two such strips together, the plaits 8 and 14 of lthe respective strips occupying staggered relations to each other, and vmutually fitting the indents 11 of their coacting plates as shown. When two such plates are thus associated together, the hexagonal cells 16 are produced, and the "endsv 17 of some of the plates are finished off, as by bendingthem inwardly to form a flat surface l: while the other ends 18 of other,y plates are finished olf, as by cutting the metalat a plait on one plate, and at an indent 15 onthe other plate, in order to form another I flat surface. After a series of cells are thus 'produced to form a radiator unit, plu-` rality of such units lare brought together, as indicated in Fig. 3, the

flat surfaces just described being secured to the plate 3,.a's` by solder or otherwise, the zigzag water pas.- sages. 5 -being left between the vertical rows of cells16, as shown. It will be observed that bythus securing a plurality of cellular units together, an entire radiator section proijrided with zigzag water courses is readilyvp'roduced, and that a plurality of sectionsmake up the radiator in the usual way. It will further` be'ohserved that the units when made are self-alining in assembling owing to their peculiar shape. In addition to the above, an exceedingly strong struc` ture may be made out of very thin material owing to the in-dentations 15 forming a firm support for the plaits 8 land 14, and thereby permitting the 'cell walls to be firmly braced. It is an `important feature of this invention that the zigzagy water courses 5 thus produced are necessarily longer than any straight water courses between the same cells could possibly be, and that therefore the water is subjected to'a reater .cooling action than could otherwise e the case.

It is obvious that those skilled in the art may vary `the details' of constructions, as well 4as the arrangement of parts without Ideparting,- from the spirit of my invention,

and therefore I do not Wish to be'limited to lthe, above disclosure except as may be required by the claims.

What I claim iszl l. ln, radiators the combination of a plate bent on itself to form a plait, then bent out Wardly and inwardly a plurality ,of times whereupon itis again bent upon itself to forni a second plait; a second plate provided.

with bends and plaits similar to Jthe first plate and having its plaits located in a .staggered relation to the irst mentioned plaits to form a plurality of polygonal cells; and means for securing said plates together, substantially as described.

2. In radiators the combination of a plate bent on itseliE to 'form a plait, then bent outwardly 'and inwardly a pluralityof times whereupon it isagain bent upon itself to form a second plait, said plate also provided. -With 1nd entations between contiguous plaits;

f a second plate provided with bends, inden*l tations and plaits similar to the first plate and havingits plaits located in a staggered relation to thekrst mentioned plaits and entering the indentations in said first mentioned 'plate to -form a plurality of polygonal cells; and ineens fory .securing said plates together, substantially as described.

ln a radiator, the combination of a plurality of cell units comprisingr a pair of op-` positely disposed plates folded to :form a series' ci laits and secured together with said' plaits of the respective plates extending in staggered relation to partition the space betwcen'said plates in to a roivol polybonal cells, the cells of one unit having pro- Vunits jecting portions adapted to coact with retreating portions between adjoining cells in -the otherl unit to form a zig-zag 4Water course; and means for securing said units in a spaced relation so as to form said Water course, substantially as described.

4. Ina radiatorthe combination of a pair of oppositely disposed lplates so bent and located relatively toeach other as to term a row of hexagonal cells separated by integral plaits extending alternatelylrom-the 'respect1ve plates, the end of one' of said plates bent inwardly to form a fiat surface,

and a supporting plate secured to said in- Wardlybent ends, substantially as described.

jacent cells inthe other unit to form a zig `zag water course, and a supporting plate se" cured to. said inwardly bent ends, substan-v tially as described.

In testimony whereof, 'l my signature, in presence 'of two Witnesses.
